    Jim,

    as it took me 3 years to get the top on, i'm not taking it off again. so this is the best i can do :)

    you can get to the bolt by the door on the front.

    the feet with the wheels on,

    the bit on the bottom is made from 1 1/2 angle (i think, i should measure it:wall:)
    that tucks under the base, the wheel have been made to stick out 6mm below this. when you screw the levelling screws down you can push them under the base. then get the ratchet strap and tighten them together. then wind the levelling screws back up.

    be careful when pushing it around, the mg-12 is VERY top heavy. wouldn't take much for it to go over.

    been playing in the shed again :D

    the beds of OD grinder come in two parts. there is the main part that is fixed and goes up and down the main bed. the other table (the one you can see) sits on top of the fixed one, but can pivot in the middle. when i was cleaning this part up it seemed a bit stiff. thought best do it proper like and take it to bits. the pic shows it was full of this rubber grindings/dust stuff.

    the work head was no better. second pic... top right is where the work head is.

    All depends what a willing buyer will pay a willing seller. lOL
    The market for cylindrical​ grinder s is very small. While CNC cylindrical grinders are still in use, manual machines are no longer made.

    Not sure how to start a new thread so I will post a reply with my new message.
    I picked up an MG12 machine that was a little rough around the edges. I have gone far enough to make everything functional and have actually done some OD grinding. The BIG problem is the leaking wheel spindle seals. The pulley side leaks so badly that I can hardly get more than a few minutes of grinding done before new oil leaks out and onto the pulley making the belt slip and slide badly. How big of a job is it to change both seals? I have sent an email off to Jubilee Machine Tools to inquire about the availability of the replacement seals and am waiting for a response.
    I have included a photo of the "as received" condition. It looks much better now but I don't have any good pictures.

    if your head is the same as my one, there are two bolts on the other side of the spindle (from the front) that you undo. The housing for the spindle is split, undoing these bolts lets the whole spindle come out the wheel side.

    i'll post some pics later to night. might explain things better.

    Hi Guys,

    A couple of years ago, I looked at one in a Birmingham dealers yard. It had been stood out in the weather for at least six months, everything that could go rusty was. It was waiting to be put into a container and shipped to India. The dealer said I could have it for £150.00p if I provided the transport to take it away. Sadly at the time I couldn't find a company who was prepared to shift it for me. It had been shipped off a few weeks later.

    I did find out that there was a group of buyers going round factories and auctions buying machines of all kinds and shipping them to India.

    sorry for the delay........

    I haven't taken the main spindle out, but it moved after i rebuilt the whole machine. then noticed i hadn't put the screws back in.
    It looks like the spindle is in a sleeve that you take out in one piece as unit. Slides out the wheel end. Inked1_LI.jpg
